The Antarctic marginal ice zone (MIZ) is the transition region between open water and consolidated pack ice, which is defined as an area with 15%-80% sea ice concentration. The MIZ represents the outer circle of Antarctic sea ice and the biological activi
The seasonal cycle of ice thickness and temperature in Lake Wuliangsuhai, a typical shallow lake in the central Asian arid climate zone, was simulated using the HIGHTSI model and the MERRA-2 data as the meteorological forcing. The average ice growth rate
Collaboration between China and Finland in marine sciences was commenced in winter 1988. The main topic was then short-term sea ice forecasting in the seasonal sea ice zone (SSIZ), particularly in the Bohai Sea in China and the Baltic Sea in Finland. The
The splitting test is a competitive alternative method to study the tensile strength of sea ice owing to its suitability for sampling. However, the approach was questioned to the neglect of local plastic deformation during the tests. In this study, splitt
The cryosphere is interconnected with other components of the climate system through global exchange of water, energy, and carbon. Long-term sustainable and pragmatic scientific and technological cooperation on the cryosphere and climatology in polar and
可燃性的聚合物电解质在发生滥用短路、机械冲击以及热失控后容易引发火灾,因此对用于锂离子电池的聚合物电解质进行阻燃改性显得尤为必要.综述了阻燃聚合物电解质的研究进展,首先介绍了聚合物电解质燃烧过程中气相和凝聚相两种阻燃机理以及阻燃性能的各种评价指标,然后概述了各类阻燃化合物的优缺点,并依据阻燃元素的不同对聚合物电解质阻燃剂进行分类讨论,最后预测了聚膦酸酯和磷腈类化合物在聚合物电解质阻燃领域的应用前景,并对阻燃聚合物电解质未来的研究方向进行了展望.
柯西不等式在酉不确定性的研究中有着重要应用,利用柯西不等式改进其本身并将其应用于酉不确定性的计算中.首先,运用以低维柯西不等式来优化高维柯西不等式的思想构造了第一个柯西不等式序列;然后,通过引入凸函数,得到了第二个柯西不等式序列;最后,将构造的柯西不等式序列应用于基于方差乘积的两个酉算子的不确定性实例研究中.结果表明,所构造的柯西不等式序列能有效地改进两个酉算子基于方差乘积的不确定性的界.
The effects of various precipitation types, such as snow, rain, sleet, hail and freezing rain, on regional hydrology, ecology, snow and ice surfaces differ significantly. Due to limited observations, however, few studies into precipitation types have been
The special issue entitled “Emerging Technologies and Their Application in the Polar Regions” will be published in December 2022 as general issue (Vol. 33, No. 4), the theme of which focuses on autonomous profiling floats; under-ice gliders (AUV and ROV);
For shallow lakes, ice mass balance is largely dominated by thermodynamic processes. The heat flux from lake water plays a critical role for ice growth and melting. In this study, we applied a numerical thermodynamic lake model to investigate the sensitiv
